How It Works

The IoT Mesh Network Agriculture System operates by distributing smart monitoring and watering tasks across multiple connected nodes using the IndusBoard/ESP-based DevBoard. At the heart of the setup, a central controller coordinates with child sensor nodes placed near individual potted plants. Each child node continuously gathers moisture data from its dedicated soil sensor. When the soil moisture drops below a pre-configured threshold, the local node can trigger connected valves for water flow control to deliver precise hydration. Because the system utilizes an ESP-based architecture with mesh networking software, the nodes can communicate with each other over extended areas without relying entirely on a single Wi-Fi router's direct range, relaying data back to the central hub. Power is supplied locally using a 3.3V battery for remote placement, while initial programming and debugging are handled via a USB Cable connected to a computer running the Arduino IDE with necessary ESP board support and mesh libraries installed.

Frequently Asked Questions

What is the purpose of using a mesh network instead of standard Wi-Fi?

A mesh network allows individual nodes to relay data through one another, extending the total coverage area of your agricultural system beyond the direct range of a single wireless router.

How do the soil sensors and valves interact with the IndusBoard?

The soil sensors connect to the board's input pins to measure moisture levels, while the board uses its output signals to control the valves for water flow when watering is needed.

Can I program this system using the standard Arduino IDE?

Yes, by installing the required ESP8266 or ESP32 board support packages and mesh networking libraries into the Arduino IDE, you can write and upload code to the IndusBoard/ESP-based DevBoard.
